New Display Panels Meet the Needs of Various Environments and Applications
The newly developed modules will be exhibited in TMD's booth at the 10th Embedded Systems Technology Expo & Conference (ESEC) at Tokyo Big Sight from May 16 through May 18, 2007, and also at the 2007 SID (Society for Information Display) International Symposium, Seminar and Exhibition at Long Beach Convention Center, Long Beach, California, USA from May 22 through May 24, 2007.
12.1-inch Module with Improved Outdoor Viewability
The 12.1-inch SVGA module, LTD121C35S, has been developed for improved viewability in an outdoor environment, which makes it ideal for point-of-sale terminals (POS), ATMs, vending machines, ticket dispensers, and other equipment installed outside. Improved viewability is achieved through ultra-high brightness of 1,000 cd/m2 featuring approximately 80 percent reduction in the surface reflection of natural light, compared to existing models. In addition, the backlight has been optimized for light utilization efficiency and heat dissipation. These improvements have been attained with only a 3mm increase in panel thickness to 14mm, compared to the 11mm of thickness of TMD's conventional 12.1-inch high-brightness industrial modules.
The mechanical mounting and electrical interfaces are compatible with TMD's conventional high-brightness 12.1-inch modules, which makes it possible to easily use the new panel in existing designs, thus enabling customers to efficiently utilize resources.
3.5-inch and 5.7-inch Modules
The new 3.5-inch and 5.7-inch QVGA (320 x 240) modules, designated LTA035A350F and LTA057A340F, respectively, are targeted for use in measuring instruments, mobile or handheld computing devices, scales, rack-mounted servers and other equipment that requires high-definition images for enhanced viewability and legibility.
The newly developed modules incorporate a high-brightness LED backlight, which eliminates the need for inverters, thus reducing electromagnetic noise. The LED backlight also contributes to a thinner and more compact module, with lower power consumption to extend battery life. Furthermore, due to TMD's original mechanical designs, the new modules accommodate side and clip mounting, and the 5.7-inch also supports rear mounting, which offers customers more flexibility for mechanical design. In addition, the newly developed modules are designed with replaceable LED backlights in order to meet the need for long-term use in industrial applications.
10.4-inch and 8.4-inch SVGA Modules
TMD's existing 12.1-inch and 8.4-inch SVGA modules have been well received by customers in the industrial sector, and there has been an increasing demand for an expanded range of SVGA resolution screen sizes. In response, TMD has developed a new high-brightness 10.4-inch SVGA (800 x 600) module, the LTA104D182F, thus expanding TMD's SVGA high-brightness series to include 8.4-inch, 10.4-inch, and 12.1-inch panels sizes, which are most frequently used in industrial applications.
In 8.4-inch size, a new module, the LTA084C191F, has been developed to meet the increasing demand for reduction in both weight and thickness for battery-powered handheld computing devices such as portable test equipment, portable medical diagnostic equipment, and industrial equipment controllers, as well as food and drink ordering terminals. The newly developed 8.4-inch module has attained further reduction in both weight and thickness while retaining the features of TMD's industrial-use LCD panels such as vibration- and impact-resistance and long-life. Compared to TMD's existing high-brightness 8.4-inch SVGA industrial modules, this new module weighs 290g (a 100g reduction) and is 6.5mm thick (a 5mm reduction).
The new 8.4-inch and 10.4-inch SVGA modules utilize TMD's core technology of low-temperature poly-silicon (LTPS), which integrates driver circuits onto the glass, thus significantly decreasing the number of connections between the glass and external circuits, and providing a stronger structure to withstand mechanical stress.
7-inch WVGA Module
The market demand for wide-screen LCD panels is growing in office equipment such as multi-function printers (MFPs), copy machines, and facsimiles, as well as in other applications such as electronic musical instruments, and point-of-sale terminals. Demand for industrial use wide- screen LCD panels is growing. These devices are increasingly required to display more information when space is limited in the vertical direction due to mechanical design. To address this need, TMD has developed a new 7.0-inch WVGA module, complementing its current 8.5-inch WVGA (800 x 480) module for industrial use.
In view of the market need, the new 7.0-inch module, the LTA070A320F, is designed with a narrow bezel and extended lamp life (life expectancy: 50,000 hours).
